Abstract
The utility model provides a nonlinear high-elastic rope shaft joint which comprises an inner hub wheel and an outer hub wheel. The nonlinear high-elastic rope shaft joint is characterized in that semi arc-shaped grooves are symmetrically arranged on the inner and the outer hub wheels, the inner parts of each pair of grooves are provided with a row of wire ropes that are in O shape, both ends of the wire ropes are fixed by fixing screws, and the end surfaces of the wire ropes are blocked by a baffle plate of the outer hub wheel in a sealing mode. The utility model which achieves the purpose of lowering the accuracy requirement of installation, no shaft generation, small radial additional acting force, etc. has the advantages of compact structure, long service life, low noise, corrosion resistance, etc.
Description
The utility model belongs to elastic coupling, also can be used as the shafting vibration vibration damper, more is applicable to the propulsion system of dynamic power machine vibration isolation peculiar to vessel in more detail.
At present, be applied in the elastic coupling of dynamic power machine propulsion system peculiar to vessel, be generally the conicalplate-coil spring shaft coupling, the shaft coupling of this kind structural type also is non-linear (load is non-linear with the elastic force of elastic element), but it is to static installation requirement height, concentrates otherwise can make conicalplate-coil spring produce stress, and noise is big, axial rigidity is very big, allows the operating time of maximum diameter, axial dynamic deformation short.
The purpose of this utility model is in order to solve the problem of above-mentioned existence, to provide a kind of wire rope non-linear highly elastic shaft coupling.It can realize reducing static installation requirement, and when shafting vibration, can effectively absorb vibrational energy the service time of shaft coupling when improving greatest axis, radial deformation, reduces bearing load, prevents resonance, reduces the fluctuation of speed, improves reliability, need not maintenance.
In order to achieve the above object, the utility model comprises inside and outside hub wheel, it is characterized in that inside and outside hub wheel circumferencial direction is provided with interior hub wheel half arc groove and outer hub wheel half arc groove, every pair of inside and outside hub wheel half arc groove symmetric arrangement, at each row's wire rope is housed in to inside and outside hub wheel half arc groove, this steel wire rope loop becomes " O " shape, and its two ends are fixed by set screw, fix by the block of outer hub wheel baffle plate and by the baffle plate set screw at end face.
Be filled with packing in the wire rope.
Protection apron is provided with radiation hole.
Advantage of the present utility model is: 1, reduced the installation precision requirement of shaft coupling, reduced the inaccurate reaction force that produces of shafting alignment, do not produce axle, additional forces radially in the carry-over moment process; 2, because this shaft coupling, mainly be that elastic element is substituted original elastic element with wire rope damper, thus the compact structure that wire rope damper had, the vibration isolation good impact resistance, high fatigue life, corrosion-resistant, advantage such as high temperature resistant; 3, the vibrational energy of axle system is to absorb by the interior friction between inner each steel wire of wire rope, so its operational noise is low, this wire rope can be worked under 270 ℃ high temperature simultaneously, can guarantee proper functioning by natural air cooled.

Fig. 3 is F, Δ X plotted curve.
(1) interior hub wheel; (2) protection apron; (3) screw; (4) wire rope; (5) outer hub wheel; (6) baffle plate set screw; (7) set screw; (8) outer hub wheel baffle plate; (9) radiation hole; (10) packing; (11) interior hub wheel half arc groove; (12) outer hub wheel half arc groove; Reaction force when F-axle, radial deformation; Δ X-axial or radially inside and outside hub wheel relative displacement.
Referring to Fig. 1, Fig. 2, hub wheel half arc groove (11) and outer hub wheel half arc groove (12) in being respectively equipped with on inside and outside hub wheel (1), (5), one row's wire rope (4) is housed in every pair of arc groove, wire rope (4) is selected the stainless steel wire rope for use, one row's wire rope (4) has 2～30 circles, always organizes several about 4～30.Wire rope (4) encloses " O " shape, and is in hub wheel half arc groove (11), fixing by set screw (7) in its two ends are pressed in.Outer hub wheel baffle plate (8) is lived the block of wire rope (4) one side and is fixing by baffle plate set screw (6); The other end of wire rope (4) is blocked by the inner face of outer hub wheel (5).Be filled with packing (10) in wire rope (4), packing (10) is generally selected wire rope or net for use, in the time of can preventing that like this impulsive load is big, causes the damage of wire rope (4).
When moment of face acted on inside and outside hub wheel (1), (5), outer hub wheel half arc groove (12) will be oppressed wire rope (4), and reaction force that its distortion is produced is realized the elasticity transmission of moment.Because wire rope (4) distortion is non-linear with the relation of elastic reactance, thereby the torque factor of shaft coupling also is non-linear.
When inside and outside hub wheel (1), (5) axially during relative movement, because the constraint of outer hub wheel (5) block and outer hub wheel baffle plate (8), one of wire rope (4) ragged edge enclosed effect before this, increase along with amount of deformation, wire rope (4) inner ring one circle circle works gradually, thereby its external performance is (as shown in Figure 3) of hard elastics.
When inside and outside hub wheel (1), (5) radially during relative movement, the free length of wire rope (4) shortens gradually with the increase of amount of deformation, and wire rope (4) is that distortion by wire rope (4) causes at radially reaction force, and this reaction force is decided by the free length of wire rope.The more little then reaction force of free length is big more, this shows, with the increase of radial-deformation, the free length of wire rope shortens gradually, so its radial reaction force is increasing, thereby its external performance also is (as shown in Figure 3) of hard elastics.By above analysis as can be seen, owing to the inaccurate installation deviation that causes shaft coupling of shafting alignment, this deviation occurs in the initial stage of distortion, and its reaction force is little, has so just reduced the installation precision requirement of shaft coupling.
The size of carry-over moment is determined by the ability and the number of wire rope itself.Characteristic curve during its carry-over moment can be controlled by the curve shape of inside and outside hub wheel half arc groove (11), (12).Hub wheel half arc groove (12) shape is analyzed in addition, radially is " length " ellipse as groove, then than circular groove want " firmly " some, radially be " weak point " ellipse as groove, then will " soft " than circular groove some.
